%N a(n) = 5*n*6^(n-1).
%C Main transitions in systems of n particles with spin 5/2.
%C Refer to the general explanation in A212697.
%C This particular sequence is obtained for base b=6, corresponding to spin S=(b-1)/2=5/2.
%C n*(b-1)*b^(n-1): for this sequence, set b=6.
%C Arithmetic derivative of 6^n: a(n) = A003415(6^n). [_Bruno Berselli_, Oct 22 2013]
